:It is an object of this invention to provide an improved conveyormechanism. 1

It is also an ob ect otthis invention to provide a conveyor mechanismhavingimproved loading and unloading mechanisms 'forhandling a pluralityof metal strips or articles of various kinds. 7 r p v It is a furtherobject of thisinventionto provide a double chain conveyoigcarryingdouble hook type carriers andhaving-means for automatically removingarticles from' said carrierstand delivering the same .into receivingmechanisms.

.It is furthermore an objectof this invention to provide a conveyorhaving double hook type carriers arranged to havealternate groups ofsaid carriers to carry twice as many ring strips as rim strips toa:kick-' off mechanism acting .to remove the ring strips and deliver thesame onto. a table While the rim strips areremovedand delivered onto aplatform.

It is an importantobject of, this invention to. provide a picklingmachine conveyor havported by a pair of connected endless chains wherebyquantities of different kinds .of'articles may" be carriedin alternategroups for selective removal therefrom.

-Other and further important objects of this invention will be apparentfromthe-disclosures in the drawings and specification.

The invention .(in a preferred vform) is illustrated inthe drawings andhereinafter -moreiully described.

therowiof tanks and are supported by a pluralityof sprockets 6 mountedon a plurality .of transversely disposed shaft-s 7 journalled insuitable bearings 8 mounted on the framework 1. Mounted upon a.framework extension 8 is a slack take-up device ,9 (Figure 1) for theendless convey- 5 or chainsfr; The sprockets 6 supporting the lowerlaps'of the conveyor chains ,5 are ar- .ranged, .asclearly illustratedin Figure 1,

for the purpose of automaticallyv delivering and removingthe articles tobe pickled in consecutive .order in. the tanks 2, 3: and 4;.

Connecting the two endless chains 5 at spaced intervals are a pluralityof trans- .versely disposed rodsor connecting bars 10 ,on each of whicha pair of spaced carriers .are pivotally..1nounted. .Each of theimproved carrierscom rises a shank portion 11 having integrally orniedthereon at right angles a pairloflparallel brackets or arms 12, each ofwhich is provided with a plurality of integral, upwardly projectingspacing teeth: or lugs 13. The carriers 12'13 are arranged in pairs andpivotally supported on the respective connecting rods of the endlessconveyors 5 so that said pivoted carriers will hang by gravity in asubstantially vertical position during their path of travel through themachine. The car-.

riers are provided with the spacing teeth 13 to permit a plurality ofrim strips or ring strips to be carried by each pair of carriers withsaid strips positioned in two parallel layers and in spaced parallelrelation. Two

sets or pairs of the carriers are adapted to frame is a reducing gear 14connected to a suitable power source and having a sprocket 15 mounted onthe shaft thereof for the purpose of driving an endless chain 16. The

drive chain'16 is also trained around a sprocket 17 securely mounted ona transverse shaft 18 also having a pair of the sprockets 6'mountedthereon for the purpose of transmitting a drive to the endless conveyorchains 5. Mounted on one projecting end of the transverse conveyor driveshaft 18 is a sprocket 19 around which an endless chain 20 is engaged.The chain 20 is also engaged around a sprocket 21 which is mounted onone projecting end of a transverse shaft 22 which is journalled insuitable bearings mounted on the discharge end' of the machine frame.Also mounted on the transverse shaft 22 intermediate the ends thereof isa sprocket 23 adapted to drive a chain 24. The chain 24 is trainedaround a sprocket 25 mounted on the middle portion of a stub shaft 26.The stub shaft 26 is journalled in a plurality of bearings'27 which aresecured to angle members 28 mounted on the machine framework. Securelymounted on the stub shaft 26 are a pair of spaced kick-oil arms 29fulcrumed intermediate their ends and spaced adjacent the inner sides ofthe conveyor chain carriers 1113, as clearly illustrated in 'Figures3'and 5. .Rigidly secured to the upright angle members 23 are aplurality of brackets 30 to afford supports for an article-receivingplatform comprising a plurality of angle irons 31, the ends of which arebent down in an inclined plane to afford a discharge apron 32. Thearticle-discharge apron 32 is provided for the discharge of the rimstrips and ring strips after they have been removed from the carriers asthey pass through the platform 31. The apron 32 projects downwardly intoa space, as indicated in Figure 4, provided for a receiving truck angleirons 34 which are secured upon a transverse table shaft 35 journalledin suitable bearings 36 on the machine frame 1, as clearly illustratedin Figure 3. The angle members comprising the stationary apron-32 of theplatform 31 project downwardly between the spaced angle members 34 whichcomprise the pivoted ring strip receiving table. The table angle members34 are connected by means of a transverse shaft'38. Secured to the endsof the shaft 38 are two bars 39 which project upwardly and have theupper endsthereof secured to arms 40 which are pivotally mounted onbrackets secured to the machine framework 1.. Each of the brackets 40carries a roller 41 which is adapted to track on a control cam '42secured on a shaft 43. Mounted on one projecting end of the shaft 43 asprocket 44 around which an endless chain 45 is trained. The chain 45receives its drive from a sprocket mounted on one projecting end of thetransverse shaft 18 which operates the conveyor chains. The cams 42 areformed and set to be operated from the shaft 43 so that at predeterminedtimes in the travel of the conveyor chains the camsacting on the rollers41 will swing the arms 40 upwardly, thereby causing the connecting bars39 to move the pivoted table 34 from its horizontal. receiving positionillustrated in Figure 4 into its elevated and dischargepos'itionasillustrated in Figure 5. A supply of ring strips which have beendeposited upon the table 34 will be discharged by gravity from saidtable when in its inclined position into a ring strip receiving truck orcontainer 46 which is adapted to be moved into the machine adjacent thetruck 33 as illustrated in Figure 4'. The cams 42 are so timed that theyact to hold the table 34 in its inclined discharging position during aperiod sufficient to permit a quantity of rim strips to be removed fromtwo sets of carriers and de posited on the platform 31 to be pushed ontothe apron 32 from which said rim strips are adapted to be discharged bygravity into the receiving truck 33 before the cams 42 perha simountedthereon a pairof transverse :bars 47 to which a pair of carrier guides"and -stops48 are secured. The upper ends of the guides 48 areinclined'to permit the lower mitithe' pivoted-table 34'tobe returned toits normal horizontal 'ring stripreceiving position.

In "Figures 1 and '7, it will-.tbe'noted that the loadingend of themachine framework cornersaof .the carrier to track thereon as they aremoved into a loading position (designated by the letter A) in Figure '7.

'Whenin loading position the carriers l lare adapted to be engagedagainst the stops or guides '48 tohold said carriers againstswinging'inwardly while they are being loaded with rim stripsor-ringtstrips.

The operation is as'follows:

The conveyor chains 5 which carry theimproved double-hook type carriers11 are adapted to be operated from the power source'through thereducingggear lethrough the chain16 which is adapted to 'drive thetransverse shaft 18 and the sprocket 17 engaged thereon. The pivoted orhanging" carriers of said conveyor chains are adapted .to follow apredetermined irregular path through the machine, said :path being 'de-'riers are now'permitted to move into load ing position to permit anoperator to load the same with a plurality of rim strips.

Aftertwo sets of carriers have'been loaded as described, with rimstrips, thethird" set ofcarriers, when moved intoloading ,position, isloaded with'a plurality of ring strips. This process or method ofloading-the car- .riers is 'followed by *the operator so thata group oftwo pairs of carriers is loaded with rim strips while an alternate groupof one The loaded carriers arexconveyed through the machine from theloading position A towards the discharge end of the machine and followan irregular path permitting the rim strips .and rin strips to belowered and carried through the pickling tank '2 after which they areautomatically'raisedand carried over into the cold Water or rinsing'tank3 "from which 1 they are automatically elevate'd and carried overintothe'neutralizing'tank' l.
